+= !VciIcu =
+
+== 1) Functional Description ==
+
+This VCI target is a memory mapped peripheral implementing
+a vectorized interrupt controller, a timer controller, and an Inter-processor interrupt controller.
+
+It can concentrate up to
+ * 32 independent interrupt lines
+ * 32 independent timers
+ * 32 IPI registers
+multiplexing to up to 32 output lines
+
+
+Complete specification is in [attachment:xicu-1.0.pdf].
